The most efficient way to solve this problem is isolating the y in the first equation because:
6x + 3y = 27
3y = 27 - 6x
y = 9 - 2x
Since all the numbers have a common factor of 3, it can be easily simplified/reduce.
If you used any other variable, you would have gotten a fraction.
Now that you found y, you can substitute it into the other equation to solve for x.
ANYWAYS, your answer is A
1/3 is actually .333333333333333333333333(repeating) so go to 33%.
Answer:
Step-by-step explanation:
1/6+1/4=5/12
5/12 of the job is done in 1 hour
so
5/12+5/12= 10/12
so 10/12 of the job is done in 2 hours
and then simplify 5/6 so then add 1/6
so it is done in 2 hours and 24 minutes
12/5 is the answer for this question, as the tangent rule is tan(theta)=opposite/adjacent. so, 24/10.
